British singer Susan Boyle said her diagnosis of Asperger’s syndrome, a form of autism, was a relief.

The 52-year-old, who rose to fame for her rendition of Les Misérables’s “I Dreamed a Dream” on Britain’s Got Talent, told the Observer newspaper that she found out a year ago that she had Asperger’s and an above-average IQ, the Associated Press reports.

“I have always known that I have had an unfair label put upon me,” Boyle said. “Now I have a clearer understanding of what’s wrong and I feel relieved and a bit more relaxed about myself.”

Boyle, who struggled in school as a child, was treated for nervous exhaustion after her famous performance on Britain’s Got Talent in 2009. She said she was happy to have a better understanding of the hurdles she faces.
